Sorry to hear about your recent experiences in the ER. If you have a history of allergies, then it is possible to have allergy induced asthma. One thing that might give you relief from the chest tightness and wheezing is using a Ventolin inhaler and if there is significant inflammation in your airways, then a steroid spray as a preventer. Did your doc ever give you these to use during the summer periods when your symptoms were worse? If your symptoms get better in the Fall, you could reduce your dose gradually.

If you have a bacterial chest infection, then antibiotics will help, however, if the cause is viral antibiotics will not work. Anyway, it is not good to take too many antibiotics, as it can leave you with lowered immunity and you will then be at risk of catching more bugs and they also strip the good flora in your gut, leaving you at risk of yeast and candida infections.

If you want a natural alternative, then I would suggest that you try acupuncture treatment or Chinese herbal medicine. Acupuncture is good for stress and anxiety and can make you feel more relaxed. It is also good for chest and breathing problems generally and can also help you to breathre more deeply from your belly rather than your chest. It can also help to clear out any infections that you may have. Brilliant for sinus infections too.

Good luck
